How Deep Argo Will Improve the Deep Ocean in an Ocean Reanalysis [PDF]
Journal of Climate, 2020 AbstractGlobal ocean sampling with autonomous floats going to 4000–6000 m, known as the deep Argo array, constitutes one of the next challenges for tracking climate change. The question here is how such a global deep array will impact ocean reanalyses. Based on the different behavior of four ocean reanalyses, we first identified that large uncertainty ...

Computer, 2022 Machine and deep learning (DL) offer significant opportunities for exploring and monitoring oceans and for tackling important problems ranging from litter and oil spill detection to marine biodiversity estimation. Reasonably priced hardware platforms, in the form of autonomous (AUV) and remote operated (ROV) underwater vehicles, are also becoming ...

The Deep Ocean's Carbon Exhaust
Global Biogeochemical Cycles, 2021 AbstractThe deep ocean releases large amounts of old, pre‐industrial carbon dioxide (CO2) to the atmosphere through upwelling in the Southern Ocean, which counters the marine carbon uptake occurring elsewhere. This Southern Ocean CO2 release is relevant to the global climate because its changes could alter atmospheric CO2 levels on long time scales ...

Nature Communications, 2022 Ocean thermal energy conversion (OTEC) resources provide a renewable solution to fuel our future. Here the authors show a significant increase of OTEC resources under greenhouse warming with the increasing rate regulated by oceanic eddies.

npj Climate and Atmospheric Science, 2023 Tropical Atlantic (TA) SST variability can impact the East Asian summer monsoon (EASM). Here, we find that the interannual EASM–TA relationship exhibits an evident interdecadal variation modulated by the Interdecadal Pacific Oscillation (IPO).

Oceanic mesoscale eddies as crucial drivers of global marine heatwaves
Nature Communications, 2023 Marine heatwaves (MHWs) are prolonged extreme warm water events in the ocean, exerting devastating impacts on marine ecosystems. A comprehensive knowledge of physical processes controlling MHW life cycles is pivotal to improve MHW forecast capacity, yet ...

The Ocean Takes a Deep Breath [PDF]
Science, 2004 Deep convection is the major mechanism for replenishing oxygen in the deep interior of the world ocean, and its variability affects the use of atmospheric oxygen to monitor the global carbon cycle. Sensors mounted on autonomous floats allow this episodic breathing of the ocean to be monitored in near real time.

Impact of geothermal heating on the global ocean circulation [PDF]
, 2001 The response of a global circulation model to a uniform geothermal heat flux of 50 mW m-2 through the sea floor is examined. If the geothermal heat input were transported upward purely by diffusion, the deep ocean would warm by 1.2°C. However, geothermal
